The product of a number and three is four less than 60. Find the number.
pantera1 [17]

hii!

n(n-4) = 60

n^2 - 4n - 60 = 0

( n   -  10  )(n   +     6  ) = 0

n-10 = 0 ---> n = 10 ---> 10*(10-4) = 10*6  = 60

n+6 = 0 --> n = -6 ---> -6 * (-6-4) = -6 * -10 = 60

4 3/4 divided by 1 1/6
ozzi

Answer:

2\frac{13}{22}

Step-by-step explanation:

=\frac{19}{4}\div \frac{11}{6}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}

=\frac{19}{4}\times \frac{6}{11}

=\frac{19}{2}\times \frac{3}{11}

\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

=\frac{19\times \:3}{2\times \:11}

\mathrm{Multiply\:the\:numbers:}\:19\times \:3=57

=\frac{57}{2\times \:11}

\mathrm{Multiply\:the\:numbers:}\:2\times \:11=22

=\frac{57}{22}

=2\frac{13}{22}
